1. Field of the Invention
2. Description of Related Art
The applicant filed an application bearing the number of U.S. Pat. No. 6,076,743, which relates to a button mounted on one side of a showerhead to select the desired types of water streams exiting the showerhead. The mechanism use in deriving the desired types of water streams is by blocking of a movable flapper to a first outlet or a second outlet. The flapper has an annular sealing packing retaining ring protruding on a surface of the flapper to provide a watertight seal when blocking the first outlet or the second outlet. However, the annular sealing packing retaining ring may be damaged due to long-term use because the rubbing against a surface defining the first outlet and the second outlet during operation. Furthermore, adding the annular sealing packing retaining ring onto the surface of the flapper requires a manufacturing process which is able to be further simplified.
To overcome the shortcomings, the present invention tends to provide a showerhead to mitigate or obviate the aforementioned problems.
